Application filed November 7, 1914. Serial No. 870,864.

To all whom it mag concern:

Be it known that 1, CHARLES FREDRIoK MENGE, a citizen of the United States, and a resident of Utica, in the county of Oneida and State of New York, have invented a new and Improved Spoke, of which the following is a full, clear, and exact description.

My invention relates to wire spokes for vehicle Wheels.

-- The object thereof is to provide a simple,

. fully described, illustrated and claimed.

In the accompanying drawings, forming part of the application, similar characters of reference indicate corresponding parts in all the views, and Figure 1 is a side elevation of my invention; Fig. 2 is a section through the soft layer, of material provided on the spoke; and Fig. 3 is an end view of the same.

Before proceeding to a' more detailed description of my invention it must be clearly understood that the layer of material can be provided on straight spokes as well as on spokes bent at the head, according to the various hubs the spokes may be applied to; that it may be used on uniform spokes as shown or on so-called swaged spokes; and that any material softer than the material of which the spoke is made can be used as a layer about the head.

Referring to the drawings, 4: represents a wire spoke, preferably of uniform diameter, the original length of the wire being sufficient to make two spokes, the ends of which are headed cold on an upsetting machine so as to form heads 5. The wire is then cut in the middle, thus forming two spokes. Each of thespokes so formed is then fitted with a sleeve 6 of material softer than the material of which the spoke is formed, and preferably into the recess provided for the head in the I sleeve, as stated. The other end of the spoke can then beprovided with thread by any suitable means.

In certain types of hubs the spoke may be used without bending the head, but for most of the types of hubs the spoke is bent at the head at a proper angle by suitable dies, which will prevent the deformation of the sleeve.

The provision of the sleeve 6 prevents change either in form, arrangement or composition of the crystals of the metal of that part of the spoke which is under strain or fatigue and, consequently, prevents the breaking of the spoke. Furthermore, the sleeve increases the resistance of the spoke at the point where it is subjected to the highest strain, as it reinforces the spoke at its bearing in the hub.

From the foregoing description, taken in connection with the accompanying drawings, the advantage of the construction of the spoke and the method of making the same will be readily understood by those skilled in the art to which the invention pertains; and while the spoke, and the method described and illustrated, I consider to be the best embodiment thereof, I desire to have it understood that it is merely illustrative and that such changes may be made when desired as are within the scope of the appended claims.

' Having thus described my invention, I claim as new and desire to secure by Letters Patent:

1. A wire spoke having a head at one end and a sleeve of softer metal than the metal of the spoke on the spoke at the head, said sleeve being rigid with the spoke and having an enlarged end adapted to rigidly engage brass is used. The bore of the sleeve is suchf l irigid therewith, said sleeve having a seat for the head of the spoke substantially as and for the purpose set forth.

3. As an article of manufacture, a wire that the same will fit tightly on the wire spoke having a head at one end and being In testimony whereof I have signed my threaded at the other end, and a sleeve of name to this specification in the presence of softer'material fitted tightly on said spoke two subscribing witnesses.

against the head to make it rigid therewith I CHARLES FREDRIGK MENGE. 5 so that the wire spoke with the sleeve there- Witnesses:
